Broad head arrowhead

ABSTRACT

A broad head arrowhead having two substantially flat, opposite surfaces converging toward a point; the surfaces being separated by a tapered cylinder in the center of the arrowhead for the reception of a shaft; a first side of the one flat surface extending beyond a first side of the second flat surface and a second side of the second flat surface extending beyond the second side of the first flat surface providing air pressures for causing rotation and stability.

According to the invention, a broad head arrowhead is provided havingtwo converging flat surfaces resulting in a broad head with four cuttingedges and essentially two blades. This unique construction results in astabilizing spin to the arrow as it passes from the bow to the target.It also presents maximum cutting with minimum resistance at the target,itself, which is especially important in hunting game.

An object of the present invention is the provision of a broad headarrowhead having a minimum of resistance to travel and penetration,together with maximum stability.

Yet another object of the invention is the provision of a broad headarrowhead which is inexpensive to manufacture and extremely effective inuse.

Other objects and many of the attendant advantages of this inventionwill be readily appreciated as the same becomes better understood byreference to the following detailed description when considered inconnection with the accompanying drawing in which like referencenumerals designate like parts throughout the FIGS thereof and wherein:

FIG. 1 is a perspective view of the preferred embodiment of theinvention;

FIG. 2 is a top view of the embodiment of FIG. 1;

FIG. 3 is a end view of the embodiment of FIG. 1; and

FIG. 4 is a side view of the embodiment of FIG. 1.

DETAILED DESCRIPTION OF THE DRAWING Referring to FIG. 1, the broad headarrowhead of the present invention is shown having a top surface 8 and abottom surface 9 converging toward a point 10. Top surface 8 has oneedge 11 extending beyond bottom surface 9 and bottom surface 9 has oneedge 12 extending beyond top surface 8. Top surface 8 and bottom surface9 are separated by a tapered cylinder 16 for the reception of an arrowshaft therein.

Referring to FIG. 2, edge 12 of bottom member 9 is shown extendingbeyond top member 8 and edge 11 of top member 8 is shown extendingbeyond edge 18 of bottom member 9.

Referring to FIG. 3, an end view is shown with tapered bore 16 for thereception of an arrow shaft therein. Shown also are sides 13 and 14 oftapered cylinder 16. Surfaces I9 and 21, due to their tapers andconvergence, create air pressures causing rotation of the arrow inflight. 7

Referring to FIG. 4, a side view is shown showing side 13, top member 8,bottom member 9, and point 10.

OPERATION Referring now to all of the FIGS of the drawing, in operationit can be seen that outside surfaces of members 8 and 9 will present aminimum of resistance to the air while providing four cutting edges. Theextensions of edges 11 and 12 beyond bottom surfaces 9 and 8,respectively, set up air pressures which result in a rotation of thearrow in flight and, at the same time, lend stability due to the flatsurfaces separating the cutting edges. This construction allows thearrow to be utilized with lighter bows and has the advantage that alledges can be sharpened, when required.

It should be understood, of course, that the foregoing disclosurerelates to only a preferred embodiment of the invention and that it isintended to cover all changes and modifications of the example of theinvention herein chosen for the purposes of the disclosure which do notconstitute departures from the spirit and scope of the invention.

The invention claimed is:

l. A broad head arrowhead comprising:

first and second flat surfaces tapering to a common point,

each of said flat surfaces having two tapering cutting edges, each ofsaid first and second surfaces has one edge extending beyond an edge ofthe other said first and second surfaces; and a tapered cylinderseparating said first and second surfaces.
